Description
Undisclosed traffic can cause the Traffic Management Microkernel (TMM) to terminate. This issue may occur when a Datagram Transport Layer Security (DTLS) 1.2 virtual server is enabled with a Server SSL profile that is configured with a certificate, key, and the SSL Sign Hash set to ANY, and the backend server is enabled with DTLS 1.2 and client authentication. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
